Cosina has announced the Voigtländer Macro APO-Ultron 35mm f/2 lens for Fujifilm X-mount cameras. While the lens is fully manual, is chipped with electronic contacts so it can transfer lens data to the camera for embedded metadata and better support for features like image correction, focus confirmation, and image stabilization on X-mount cameras with in-body image stabilization (IBIS).

The 35mm f/2 is described as a standard macro lens with a large aperture. It is constructed of nine elements in six groups and includes three “abnormally dispersed glasses.” The apochromat design promises natural color development without color bleeding (as well as the suppression of axial chromatic aberration and chromatic aberration) and Cosina says the overall size of the optic is relatively compact especially given the wide open aperture and macro capability.

The company says the optical system is optimized for the image sensor of the Fujifilm X-series of cameras, and issues such as distortion, dimming, and color cast in the peripheral areas of the image have been suppressed without requiring optical correction from the camera.

The lens is fully manual, with Cosina’s all-metal helicoid unit adjusted with high precision and high-quality grease that produces what it describes as appropriate torque. The result is what Cosina describes as a focusing operation that is smooth yet responsive enough for fine focus adjustments. As with the Voigtlander VM mount and mirrorless mount lenses, the company says the aperture ring uses a mechanism that is directly connected to the opening and closing of the aperture blades, which allows a photographer to feel the operation of the mechanism directly.

The lens features an aperture range of f/2 through f/22 via a 10-bladed aperture diaphragm. Cosina says that this high number of blades results in a more circular-shaped out-of-focus area, or bokeh.
